Machine drive

A drive motor, not shown, is at a standstill

, .. "via an intermediate transmission with the driving part 60 / Fig. 3 and 5) a coupling in connection, which rotates on a fixed pin 61 of the machine frame and a gear that can also be rotated on the pin 61

- ·. can take along coupling part 62. The coupling part 62 is, however, normally held in the rest position by a locking lever 63 which is rotatably seated on a fixed pin 64 of the machine frame, is connected to a control lever 65 and normally lies in front of a shoulder of the driven coupling part 62 ... ■: .... - A _ upwardly extending extension of the control lever 65 includes with a fork slot a pin 66 * of a push rod 67, the right end of which is guided in Fig. 3 on a pin 68 of the machine frame and the left end on one on a Shaft 70 rotatable disc 69 is articulated. A pin 71 (Fig. 3) of an arm 72 rotatable on a pin 73 of the machine frame normally engages behind a shoulder of the disc 69 and thereby holds the locking lever 63 against the force of a spring 74 in the operative position.

When a motor button 75 is depressed, which can be displaced with two longitudinal slots on two fixed pins 77 and 78 of the machine frame and with a third slot comprises a pin 79 of a lever So rotatable on the pin 77, the lever cSo is rotated counterclockwise, whereby his pin Si, which engages in the fork slot of a lever 82 which is rotatable on the pin 72, rotates this in a clockwise direction. The lever 82 comprises with two fingers & 2 and 84 (Fig. 4) a bend 85 of a slide 86 which is slidably arranged on pins of the arm 72 with two longitudinal slots.

A spring 87 tensioned between the arm 72 and the slide 86 seeks to hold the bend 85 normally in engagement with the fingers 8s and 84 so that the arm 72 is carried along when the lever 82 is rotated clockwise. The clockwise rotation of the arm 72 removes the pin 71 from the area of the shoulder of the disc 69, so that the spring 74 disengages the locking lever 63 from the shoulder of the driven part 62 and thereby allows it to be carried along by the driving part 60. The counter-pointer rotation of the locking lever 63 closes the motor circuit at the same time in a manner not shown.

An arm 88 is connected to the driven coupling part 62 (FIG. 3) and is connected by a rod 89 to an arm 90 fastened ^{on the main drive shaft 91.} Via parts 88 and 89, a full counterclockwise rotation of coupling part 62 is converted into a reciprocating motion of arm 90 and shaft 91 of approximately 60 °, arm 90 and shaft 91 initially swinging counterclockwise and then return to the normal position. This one-time back and forth movement of the main shaft 91 is sufficient to carry out an addition, a subtraction or a -. Sum drawing process from. As a result, in the last quarter of the revolution of the driven coupling part 62, a lifting edge of the arm 88 hits a roller 93 on a lower extension of the control lever 65 and swings this and the locking lever 63 connected to it clockwise. As a result, on the one hand, the locking lever 63 comes back into the path of the shoulder of the driven coupling part 62 and, on the other hand, the *.

Paragraph of the disc 69 above the pin 7i, so that the arm 72 and the lever 82 by a spring-loaded arm 49 in their normal position be returned. The now S reaching behind the shoulder of the disc 69 again Pin 71 holds the parts in the position shown in Fig. 3, even when the lifting edge 92 has left the role 93 again.

The counter-pointer rotation of the arm 72 and the lever 82, the lever 80 is in the Clockwise, turned, of the engine button 75 returns to the unpressed position. When the disk 69 moves back clockwise its edge 94 (Fig. 3) meets a pin 95 (see also Fig. 4) of the slide 86 and brings the bend 85 into the Area of an L-shaped recess formed by fingers 83 and 84. Should the If the motor button 75 is inadvertently held down, the arm 72 can still be operated independently from the lever 82 rotated in the opposite sense and the pin 71 under the paragraph of Disc 69 are brought to prevent unintentional passage through the machine impede.

Keypad and amount switch works

The keypad of the machine serving as an embodiment comprises several Rows of amount keys 10.1 (Fig. 1 and 9), a series of gait keys 102 and a stand-alone addition key 103.

By pressing an amount key 101 (Fig. 9), a square pin 105 located on its shaft moves in a known manner into the path of an associated shoulder 106 of an amount switching element 107. On each ~ ^; Key shaft is also a pin 115, which cooperates with the inclined edge of a locking hook of a locking slide 116 guided between four rollers 117 seated on fixed pins, and this when pressed. "A button 101 is moved to the right against the force of a spring 118 according to FIG. 9. The spring 11 & is between the locking slide

116 and one-also between the roles

117 guided control slide 119 cocked. When the pin 115 · under the associated Hook of the locking slide 116 arrives, the spring 118 leaves the hook over the pin 115 grab, making the key in the depressed Location is held. When an amount key is depressed, its pin 115 also works with a lifting edge of a recess of the control slide 119 together and moves it against the force of the spring

118 to the left. With this left movement If the control slide 119 encounters a bend in one that is rotatable on a transverse rod 121 Zero stop pawl 120, turns it in the opposite direction clockwise and disengages it from one of the amount switching elements 107 located approach 122. One between the control slide 119 and the Zero stop pawl 120 tensioned spring 123 keeps the bend of this pawl in contact with the left end of the as shown in Fig. 9 Control spool 119. If in a row no amount key is pressed, the zero stop latch 120 holds together with the Approach 122 the amount switching element 107 during the machine gear in the zero position fixed.

A pin 125 engages in a vertical slot 124 of each amount switching element 107 a three-armed lever 126 rotatable on the shaft 127 Spring 128 normally keeps this in contact with a bracket 129, the is supported by two arms 130 attached to the shaft 127. A rod 131-connects the arm of the lever 126, which extends to the right according to FIG. 9, with a type segment 58, which is rotatably seated on an arm 132 rotatable on the shaft 133.

If the arm 90 (Fig. 3) is swung out in the manner described, one slides roller 134 located on it in a bayonet-shaped cam slot 135 (Fig. 2) one on the shaft 127 mounted arm 136 and thereby pivots the shaft 127 with the Bracket 129 (Fig. 9) first in a counter-clockwise direction to bring it into the normal position bring back. During its counterclockwise pivoting movement, the Bracket 129 over springs 128 in any place the lever 126 and the amount switching element 107 with until its paragraph hits the pin 105 of the pressed key 101. By this right movement of the amount switching element 107 is via the lever 126 and the Rod 131 the type segment 58 accordingly set by pressing the amount key. After the amount switching element 107 through one of the square pins 105 is stopped, the bracket 129 completes its full stroke, whereby the spring 128 is tensioned. On the same pin as roll 134, but on the other side of the arm 90 sits a roller 164 (Figs. 2 and 8), which with the cam groove 137 one mounted on a shaft 139 Armes 138 cooperates. Two arms 140 (Fig. 9) are also attached to the shaft 139, which carry a locking bar 141 extending over all amount switching mechanisms. Towards the end of the counter-pointer swiveling arm 90, the swivels. Roll 164 the arm 138 and shaft 139 clockwise, wherein the locking bar 141 enters the locking teeth of the lever 126 and these as well as the amount switching elements 107 and the

Type segments 58 holds in the set position.

Immediately thereafter, the shaft 133 is rotated to in a known manner the To let type segments 58 hit against the paper roller 56. The arm 90 carries one Pin 110 (Fig. 21), which is used in all operations with the exception of the coating operations of a recess at the lower end of a coupling rod in is included. The coupling rod in is rotatably seated on an arm 113, which is rotatably mounted on a shaft 133 attached arm 114 is arranged and. whose extension by springs with the shaft 133 is kept in touch. When the arm 90 rotates in the opposite direction, the Stems as well as arms 113 and 114 the Shaft 133 and a bracket attached to it

160 (Fig. 9) rotated clockwise to place one between bracket 160 and one at pawl 162 located on each arm 132 is switched on Tension spring 161. Are the feathers

161 is sufficiently tense, so becomes in itself As is known, one that holds the arms Ύ32 tight Locking bar 149 disengaged, so that the springs 161 of the intended for the impression Type segments 58 can take effect. When the arm 90 moves back the shaft 133 rotated counterclockwise. Bring one of the hanger 160 supported crossbar 151 the arms 132 back to the position shown in Fig. 9. Next, the locking rail 141 from the associated Locking teeth disengaged and the bracket 129 rotated clockwise, which the Lever 126 and the amount switching elements 107 returns to the normal position. Before the Return of the amount switching elements 107, the locking slide 116 is moved to the left, to trigger the pressed amount keys. After triggering, the control slide 119 also resume their normal position a, so that the zero stop pawl 120 over the lugs 122 of the amount switching elements 107 grab and hold them in the zero position.

Arithmetic and adding units

The machine serving as an exemplary embodiment has one for addition and subtraction suitable arithmetic unit no. 1 and three adding units, which are shown in Fig. 9 with no. 2, no., 3 and 'no. 4th are designated. Each amount switching element 107 has two gears, the arithmetic unit No. 1 and the adder No. 2 are assigned, and is provided with an extension piece 155 connected, the teeth of which work together with the addition units No. 3 and No. 4.

In addition processes, the wheels of the selected adding unit (s) are included in the Toothings of the amount switching elements 107 or their extension pieces 155 engaged, after these have ended their right-hand movement, and remain with them during the return of the amount switching elements 107 engaged. Thereby the indented arithmetic units or adding units are reversed advances the amount set on the amount keypad. Have the amount switching elements 107 resumed their normal position with their extension pieces 155, so the selected arithmetic and adding units are disengaged.

In the case of subtraction processes, the wheels of the arithmetic unit no. 1 become the amount switching elements 107 indented before they begin their rightward movement. This will be the calculating wheels in the opposite direction according to the amount set using the amount keys Turned senses like in an addition process. The calculating wheels are disengaged from the amount switching elements before they begin their return movement to the zero position.

In the case of summation processes, the wheels of the selected arithmetic unit or adding unit at the same time in the amount switching elements 107. λνΐε engaged with a Subtraction process and turned back until known, also for purposes the counter-tens serving for tens transmission are stopped. Has this happened so the amount switching elements 107 and the type segments 58 are on that amount set, which was previously on the now at zero arithmetic or adding unit found. In the case of totals pulls, the wheels of the are reset to zero Arithmetic or adding unit disengaged from the amount switching elements 107 before these begin their return movement to the normal position. The arithmetic or adding unit consequently remains at zero. In the case of a subtotal pulling process, that remains Selected arithmetic unit or adding unit also during the return movement of the amount switching elements 107 with these in engagement, so that it is the previously removed amount resumes and, therefore, at the end of the subtotal drawing process on the same The amount is set as before the start of this process. '

Adding factory back device

In the following, only the engagement device for the arithmetic unit no. 1 is described. It is essentially the same for the other three adders.

The shaft on which the calculating wheels of calculator no. 1 are arranged is in one of two on fixed pegs 158

(Fig. 17) rotatable 'side walls 157 and housed a cross piece 159 existing swing frame. Each side wall 157 , · Carries a roller 165 that fits into a cam slot 166 one each on an adder engagement shaft 168 attached lifting disk 167 engages. On the engagement shaft 168 is an arm 169 is also attached, which is connected by a push rod 170 with a lever 171 (Fig. 15) connected is. The lever 171 is rotatably seated on a pin 172 of an engaging disk 173 mounted on the main shaft 91 and carries on the engagement pin of the push rod 170 a driving pawl 174, which is held by a spring 175 with a stop pin of the lever 171 is kept in touch. An upward extension of the pawl 174 works with a pin 176 of an angle lever 177 rotatable on a fixed pin 178 together. The pin 176 is supported by a fork slot of a push rod 179 (Fig. 15 and 16), the lower end of which is attached to a lever rotatable on a fixed pin 181

_t 180 is hinged. With the lever 180 is a

»5 slider 182 connected to the edge of the sheet 183 of the engagement disk 173 cooperates.

If the paper trolley is set to a column in which the arithmetic unit no. 1 for If addition is to be selected, a paper trolley stop, not shown, lifts a rod 184 (Fig. 15), the lower The end engages a control pawl 185 rotatable on a fixed pin 186. By the upward movement of rod 184 rotates pawl 185 in a counterclockwise direction and removed from the path of a shoulder of the bell crank 177. The disk 173 becomes for addition, subtraction and sum

4Q drawing processes through the shaft 91 initially according to Fig. 15 and. 16 swung clockwise and then returned to the normal position. At the beginning of the clockwise rotation of the disk 173, its curved edge 183 leaves the slider 182 so that the lever 180, the push rod 179 and the angle lever 177 can be adjusted by a spring 187 which rotates the angled lever 177 counterclockwise and thereby the pin 176 removed from the path of the extension of the driving pawl 174. In the further course of the clockwise rotation of the disk 173, the lever 171 rotates in the opposite direction around the pin 172 until a square pin 189 of the disk 173 strikes an extension 188 of the pawl 174, so that the lever 171 is now on the further clockwise rotation of the disk 173 must participate. This movement of the lever 171 leads via the push rod 170 to a counter- pointer rotation of the arm 169, the shaft 168 and the cam disks 1 6γ. When they rotate in the counter-pointer, the cam disks 167 (Fig. 17) pivot the arithmetic unit frame clockwise by means of their cam slots 166 via the rollers 165 and bring the arithmetic units into engagement with the teeth of the amount switching elements 107 after they have finished their setting movement. This intervention remains while the amount switching elements 107 are returned to their normal position, the calculating wheels being rotated according to the amount keys pressed.

After the amount switching elements 107 have ended their return movement, which happens during the reverse movement of the shaft 91 and the engagement disk 173 in the counterclockwise direction (Fig. 1.5), a pin 190 of the disk 1 73 hits a projection of the lever 171 and swings the Arm 169 and the shaft 168 clockwise to disengage the wheels of the arithmetic unit no. 1 from the amount switching elements 107. Towards the end of the counter-pointer rotation of the disk 173, its curved edge 183 meets the slide 'piece 182 and pivots the lever 180 clockwise, which turns the angle lever 177 clockwise via the push rod 179 and the pin 176 until the pawl 18 5 is behind again whose sales are falling.

If the paper trolley is brought into a position in which the arithmetic unit for addition is not selected, the pawl 185 (Fig. 15) remains in its effective position, prevented So a counter-pointer rotation of the angle lever 177 and holds the pin 176 in the path of the extension of the latch 174. The Pin 176 leads to the start of clockwise rotation the disk 173 a clockwise rotation too the pawl 174 brings about, whereby the extension 18S removed from the path of pen 189 will. As a result, arm 169 and shaft r68 are not rotated counterclockwise and the calculating wheels are not engaged with the amount switching elements 107.

By pressing the calculator no.1 associated addition key 103 (Fig. 1 and .15), the latch 185 is also in itself in a known manner brought into the ineffective position.

Subtraction key

By pressing a subtraction key in gait key row 102 (Fig. 1 and 15) a recess 191 located on its shaft reaches the area of a bend 192 of an arm rotatable on a pin 194 193, so that its loading spring 195, which is normally its bend 192 in Be iac running with the shaft of the subtraction key, turn it clockwise

can. When the arm 193 rotates clockwise, its extension meets a pin 196 one also rotatable on the pin 194 Lever 197 and takes it with it. When the lever 197 is turned clockwise, a acts its lower end located pin 198 on a bevel of one on a solid Pin 200 rotatable control lever 199 a and swings this out clockwise. Dato get through the ends of two spring-loaded Stop pawls 201 and 202 in the path of the lower arm of the lever 171, such as in Fig. 15 indicated by dash-dotted lines.

At the beginning of the clockwise centering of the disk 173, the lower part 203 now meets of the lever 171 on the pawl 201, so that the arm 169 and the shaft 168 against the Turned clockwise (Fig. 17) and the calculating wheels in the amount switching elements 107 be engaged before they have started their adjustment movement. With the now following Adjusting movement of the amount switching elements 107 are the calculating wheels accordingly the pressed amount keys are turned back- »5, whereby the subtractive introduction of the amount into the arithmetic unit Xr. 1 takes place. After the calculating wheels in the amount switching elements have been engaged, the lower end of the lever 171 comes on further Course of the clockwise rotation of the disk 173 out of the path of the stop bars 201 and slides towards the end of the clockwise rotation of the disk 173 over the stop pawl 202, as indicated by dash-dotted lines in Fig. 15. While the amount switching elements 107 in their set position still remain, the return movement of the disc begins 173 in the opposite direction. The part 203 of the lever 171 hits from the right the pawl 202, which rotates the shaft 168 clockwise and the rake wheels are disengaged from the amount switching elements 107. Immediately after this the arm becomes 193 (Fig. 15) by the button release device Swung out counterclockwise, causing the bend 192 to come out of the recess 191 is removed so that the subtraction key 102 under the action of their loading spring their unpressed position and the lever 197 under the action of its loading spring 211 can take up its normal position again.

Fig. 11 shows the highest digit calculating wheel 204 with the associated additional ten counter pawl 205 and the associated subtraction ten counter pawl 206, which with a decimal connected to the calculating wheel 204

- nerscheibe 207 cooperate. Since the calculating wheel 204 has twenty ¹ teeth, the tens disk 207 has two teeth. In the case of subtraction processes, the addition counter pawl 205 is removed from the path of the tens disc 207 and the subtraction counter pawl 206 is simultaneously brought into the path of the tens. Such a device is provided for the calculation wheels of all places.

The clockwise rotation of the lever triggered by pressing the subtract key 102 197 (Fig. 15) is turned over a rod 208 in a counter-clockwise rotation one on one Pin 21 5 converted to rotatable angle lever 209 (see also Fig. 8). This will a pen on one arm

216 from the lower edge of a hook 217 removed, which is rotatably attached to a lever mounted on a decimal switch shaft 219 218 is seated. As a result of the downward movement of the pin 216, a spring 220 leaves the hook

217 via a pin 221, which is the push rod 170 connects to the arm 169, grab. Will now start to turn clockwise the disk 173, the arm 169 and the shaft 168 rotated counterclockwise, the pin 221 pivots the lever via the hook 217

218 and shaft 219 clockwise until a square pin 210 at the lower end of the lever 21S above the shoulder 222 a pawl 223 arrives. The pawl 223, which is rotatable on a fixed pin 224 is seated, can now turn clockwise under the action of a torsion spring 225, so that the paragraph 222 lies behind the pin 21 ο and the lever 218 and the Holds shaft 219 in the misaligned position. This clockwise pivoting of the switching shaft

219 in the position according to Fig. 11, its protruding bar 226 is removed from the extensions 227 of the subtraction counter-pawls2o6 so that these, under the action of their loading springs, come into the path of the tens teeth of the disks 207. In addition, the bar 226, in cooperation with the lifting edges of the addition ten counter pawls 205, removes them against the force ^> 0.5 of their loading springs from the path of the tens teeth of the disks 207, so that the addition ten counter pawls 205 remain ineffective during a subtraction process. During all other processes, the subtraction ten counter pawls 206 remain ineffective.

Towards the end of the return movement of the engagement disk 173 (Fig. 151 in the counter-clockwise direction hits, its pin 22S on an extension of a lever rotatable on the pin 181 229 and turns it clockwise. In doing so, a pin 230 of the lever 229 wiggles up an extension of the pawl 223, rotates it slightly counterclockwise and removed the paragraph 222 of the square pin 21 o, so that the lever 218 and the shaft 219 under

the effect "of a spring 231 their illustrated To be able to resume normal position. This normal position is determined by the fact that the Square pin 210 is in a recess 232 of the pawl 223 is inserted. A fixed pin 233, which, in a recess in the lever 229 reaches into it, limits the deflection of this lever.

. Totals drawing operations

Sum operations are similar to subtraction operations, with the only difference that that about inadvertently pressed amount keys are automatically triggered at the beginning of the machine operation and the tens transmission device remains set to addition.

By pressing the balance key in row 102 (Fig. Ι and 15) an exception

ao mung278 of their shaft into the path of a Abiegimg 279 of an arm 280 rotatable on a fixed pin 281, so that this under the action of a spring 282, rotate clockwise and the bend 279 in

* 5 the recess 278 can enter. During this clockwise rotation, a downward one takes Extension of the arm 280 via a pin 283 also on the pin 281 rotatable lever 284 with whose pin 285 at its lower end by cooperation with a lifting edge of a Suinmenzugsteuerhebels 286 rotatable on the pin 200 this . also swings clockwise. The lever 286 engages below with an extension a pin 287 of the subtraction lever 199, raises this and brings the pawls 201 and 202 in the area of part 203 of lever 171.

In the same way as with subtraction operations, hits at the beginning of the clockwise rotation of the engagement disk 173, the lower end 203 of the lever 171 onto the stop pawl 201, so that in the further course of the clockwise rotation of the disk 173 the shaft 168 rotated counterclockwise and the Wheels of the arithmetic unit are engaged in the amount switching elements 107 before they are removed from their zero position. With the movement of the amount switching elements now beginning 107-according to Fig. 9 to the right, the calculating wheels 204 are counter-clockwise or rotated clockwise according to Fig. 14 until one of the tens teeth of the disk 207 of to the left meets the ten counter pawl 205.

In this way, the amount switching elements 107 and the type segments 58 are on the amount set, which was previously on the calculating wheels 204. While the amount switching elements 107 remain in their set position, hits at the beginning of the reverse rotation of the engagement disk 173 of the part 203 of the lever 171 on the stop pawl 202 to the To disengage arithmetic wheels from the amount switching elements. The return movement that is now taking place the amount switching element 107 has no influence on the position of the calculating wheels, so that these remain in their zero position. Towards the end of the total drawing process, the arm 280 (Fig. 15) is in a known manner disengaged to release the balance key, so that a spring 288 counteracts the lever 284 can rotate clockwise, causing the stop pawls 201 and 202 off track of the part 203 of the lever 170 can be removed.

Is the balance key together with the subtotal key in row 102 is pressed, the arm 280 is disengaged immediately after the amount switching elements 107 have finished their adjustment movement. As a result, the pawl 202 is already closed this point in time from the path of the part: 203 removed so that the calculating wheels with the Amount switching elements 107 remain engaged during their return to the rest position. Only after the amount switching elements 107 have resumed iKre = rest position, the calculation wheels are disengaged as in an addition process.

Coating device

The machine serving as an exemplary embodiment is intended for the management of debit accounts. If the account holder pays in more than what corresponds to his debt, and if the amount deposited is deducted from the debit amount on his account, an overdraft arises. This is now a loan amount for the account holder. An overlay appears in the arithmetic or balancing work No. ι as a complement number. In order to bring it to the imprint according to its real size, the complement number has to be converted into the actual coating. For this purpose, either the intermediate credit balance key 331 or the credit balance key 332 (FIG. 1), which could also be referred to as the overdraft or intermediate overdraft key, is pressed.

If one of the two keys is pressed, the machine performs four main wave games the end. When drawing a subtotal credit balance, during the first machine game the complementary value of the coating removed from the arithmetic unit no. 1 and introduced additively into an auxiliary storage unit. During the second main wave game the complementary amount is taken from the auxiliary storage unit and subtracted introduced into arithmetic unit no. 1, which is set to zero, so that it is now the actual Includes coating. During the third main wave game, the actual

. Cover taken from the arithmetic unit no. Ι and introduced into the auxiliary storage unit in order, during the fourth main wave game, to: to be introduced subtractively into the arithmetic unit no. ι, which is at zero, so that this in turn contains the original complement amount of the coating. While of the last main wave game, the actual coating is also imprinted.

ίο If, on the other hand, instead of key 331, the If key 332 is pressed, the first three main wave games in the already take place described way. During the fourth main wave game, the actual over-

Credit balance

and inter-credit balance key

The credit balance key 332 is at the lower end of its shaft with a fork slot on a fixed pin 333 and guided with a longitudinal slot on a fixed pin 334 (Figs. 22 and 23). A spring 335 (Fig. 23) seeks to pull the button upwards and keeps the shoulders of its shaft in contact with the underside of the keypad plate 76.

The shaft of the sub-credit balance key 331 is on pins with parallel slots 336 and 337 (Fig. 21) of the shaft of the button 331 out and includes with one on his At the lower end of the fork slot the pin 333. A spring 338 searches for the button

331 upwards and normally holds Steps of their shaft in contact with the underside of the plate 76.

Are the two buttons 331 and

332 in their unpressed position (Figs. 3 and 6), the pins 336 and 337 are in contact of the button 332 the upper end edges of the longitudinal slots in the shaft of the button 331. As a result, the key 331 always takes the key 332 with when pressed, while the key 332 can be printed independently of the inter-credit balance key 331.

A plate 339 (Figs. 19, 22 and 23) has a longitudinal slot at its lower end guided on the pin 333 and carries a pin 340, which passes through a slot in the shaft the button 332 protrudes and on the rotatable a coupling pawl 341 sits .. One Spring 342 seeks to rotate the coupling pawl 341 counterclockwise and holds thereby their bend 3 43 in engagement with a recess of the button 332. A second Pin. 344 protrudes with its pin through the plate 339. About this peg is a socket 345 of approximately the same diameter as that of the pin 344 pushed (see especially Fig. 22).

When the button 332 is depressed, the plate 339 is carried along via the pawl 341. The pin 344 (Figs. 22 and 23) meets an extension of one on the pin 333 rotatable pawl 346 and swivels it against the force of the loading spring 347 counterclockwise. This will hook the pawl 346 off a turn

348 of a lever rotatable on the shaft 70

349 (Fig. 23) removed. The lever 349 is through a tab 350 with an on one Shaft 352 (see also Fig. 8) attached angle lever 351 connected. Is the latch 346 away from the lever 349, so pivots a spring 353 attached to one arm of the Angle lever 35r engages, this, the shaft 352 and, via the bracket 350, the lever 349 clockwise until its roll

354 against the circumference of a lifting disc

355 leg ¹ · The lifting disk 355 belongs to a set of rigidly connected lifting disks (Fig. 26), which are accommodated on a bushing 356 rotatable on the pin 73. As a result of the aforementioned clockwise rotation of the shaft 352, the arithmetic unit no. 1 is selected in a manner still to be described for a summation process.

If the plate 339 is moved downwards when the credit balance key 332 is pressed, it hits furthermore the socket 345 (Figs. 21 and 22) on an extension of a pawl 357, it pivots counter-clockwise against the force of their loading spring 360 and removes their Hook from the bend 358 of a lever 359 rotatable on the shaft 70. As a result the lever 359 can rotate clockwise under the action of a spring 365, until its roller 366 is against the circumference of a cam disk 367 of the on the bush 356 (Fig. 26) attached lifting disc set. A tab 368 engages the lever 359 (Fig. 3), in the longitudinal slot of which a pin 369 of the lever 80 engages. Consequently is rotated by the clockwise rotation of the angle lever 359 on the tab 368 of the lever 80 in the counterclockwise direction, the in turn rotates lever 82 and arm 72 clockwise and pin 71 of the shoulder of the disc 69 removed, thereby starting in the manner described the machine takes place. 1 * 5

As already described, the lifting edge 92 of the arm 88 pivots in cooperation with the roller 93 the lever 65 at the end of each clockwise rotation to the To bring disk 69 in such a position that the pin 71 again behind its heel can grab. However, since a coating preference

gang consists of four machine games, imiss can be prevented that the pin 71 is behind the shoulder of the disc. 69. For this reason, the clockwise rotation of the Lever 359 an extension of a pin 369 one on the. Pin 107 rotatable pawl 370 removed the hook 372 under the action of a spring 371 behind the pin 71 engages when it is removed from the shoulder of the disc 69.

A pin 373 (Fig. 21) of the lever 359 engages in the longitudinal slot of a rod 374, which engages the coupling rod 111 at 375. So if the lever 359 is rotated clockwise by the spring 365, then the coupling rod 111 via the rod 374 pivoted counter-clockwise and out of engagement with the pin 110 of the arm 90 and brought into engagement with a fixed pin 376. As a result, the pressure shaft during the first three machine games a coating process is switched off by the machine drive. Towards the end of the third The machine game of a coating process is lever 359 through the Hubscbeibe 367 set back in the counter-clockwise direction. It is a lever 359 and the Spring 377 connecting rod 374 tensioned, which the coupling rod in, when, towards the end of the third working cycle, the pin 110 is in the path of the recess the coupling rod has entered; these

. Can reach over the pin 110 so that the Printing unit works during the fourth work cycle of a coating process and the prints true coating,

By resetting the lever 359 (Fig. 3) in a counter-clockwise direction, the Pin 369 removed the pawl 370 from the pin 7.1. However, since the pawl 37a is only disengaged after the lifting edge 92 of the arm 88 has already left the roller 93 again, the locking pin 71 only take effect towards the end of the fourth machine game.

About overturning control disks

The pin 337 (Fig. 6) of the shaft of the credit balance key 332 engages in a horizontal slot of a _; Coupling pawl 378 which is rotatably seated on an arm 379 fastened on the shaft 91 and whose recess 380 can grip via a pin 381 of a slide 382. The slide 382 is guided with fork slots on the shaft 91 and the pin 73 and can be connected to the shaft 91 by the coupling pawl 378 so that it is moved back and forth once for each machine game, i.e. four times for a coating process.

Two ratchets 383 and 384 are rotatably seated on the slide 382 (Fig. 7), whose pins protrude into ^ bores of the slide 382 and the through a Spring 385 are interconnected. The spring 385 holds the pawl 383 so that that their switching tooth can work together with four dovetail-shaped recesses 386 of an indexing wheel 387, while one tooth of the other pawl 384 is in engagement with each of the four teeth 388 of a second ratchet wheel 389 is. The two ratchet gears 387 and 389 that go through a disk 390 (Fig. 26} are separated from each other, are connected to those on the socket 356 attached lifting disks 355 and 367 and one the engagement and disengagement of an auxiliary storage unit effecting cam disk 391 rigidly connected.

When the slide 382 is moved to the left (Fig. 7), the pawl 3S3 comes into engagement with one of the dovetail-shaped recesses 386 and rotates the sleeve 356 with the parts attached to it counterclockwise by approximately 60 °. During the return movement of the slider 382 to the right applies _f the pawl 384 to a tooth / 3 88 of Fort ratchet wheel 389 and rotates the mounted on the bushing parts to approximately 30 °. Since the sleeve 356 is rotated through 90 ° in one working cycle, four working cycles are required for a full rotation. A spring-loaded pawl 392, which is rotatably seated on the shaft 70, interacts with the ratchet wheel 387 and prevents the lifting disk set from rotating backwards.

The dovetail-shaped recesses of the ratchet wheel 387 prevent them from merging with the pawl 383 an advance of the lifting disk set when the lifting edges of these disks meet the rollers of the spring-loaded ones Levers 349 and 35b face each other. A tooth extending downwards 393 (Fig. 7) of the pawl 383 serves, in cooperation with the circumference of the Ratchet wheel 387 the ratchet tooth of the pawl 383 towards the end of the left movement from the Remove recess 386 to allow pawl 383 to rotate under the action the pawl 384 does not prevent.

The credit balance key 332 (Fig. 3) remains until: the end of the fourth work cycle Überaigsvorganges pressed, whereupon it is triggered and -under the action of the spring 335 resumes its normal position. As a result of this return of the credit balance key 332 in the unpressed position, the coupling pawl 378 releases the pin 381 so that the Slide 382 is not moved during operations other than coating.

Holding device for the credit balance and interim _{credit (o} balance key

The inter-credit balance key 331 and the credit balance key 332. (Figs. 21 and 23) are provided with bends 394 and 395, which are rotatable on a fixed pin 397 with a and pawl 396 loaded by a spring 398 cooperate.

If either the 'fast 332 is pressed alone or the buttons 331 and 332 are pressed together, so either the turn 394 alone or the turns 394 and 395 at the same time below the locking paragraph 399 'of the pawl 396, whereupon the spring 398 the Blocked heel 399 via the turn-off 394 alone: or via the turn-offs 394 and 395. greia'5 fen to a return of the pressed key or keys under the action of the Spring 335 or 338 to prevent. When the credit balance key 332 is depressed alone, so A blocking surface 400 of the pawl 396 comes under the turn 394 to the inter-credit balance key 331 to lock against depression. The pawl 396 has another Paragraph 401, which cooperates with a pin 402 of a pawl 403 (Fig. 25). the The pawl 403 is rotatably seated on a pin 112, which connects the coupling rod 111 with the Arm 113 connects, and is normally attached to a stop pin by a spring 405 404 of the arm 113 held in contact.

During the first three work cycles of a coating process, during which, as already described, the coupling rod 111 itself is out of engagement with the arm 90.

the pawl 403 remains in its normal position, so that the pawl 396 is also effective The situation persists and the credit balance or, at the same time, the interim credit balance do hold the button in its depressed position.

If, towards the end of the third machine game of a coating process, the coupling rod m is again engaged with the pin 110 and the coupling rod is now moved upwards at the beginning of the fourth machine game, the pin 402 comes above the shoulder 401 and is removed when the coupling rod moves downwards 111 the locking boxes 399 of the pressed key or keys so that they can resume their unpressed position. In order to keep the pawl 396 in the release division if one of the buttons 331 or 332 is accidentally held down at the end of a coating process, a pawl 406 (Fig. 23 and 5 28) is seated on the fixed pin 334, which is activated by the spring 398 ( see also Fig. 21) connected to the pawl 396. Under the action of this spring, the upper end of the pawl 406 rests against the upper edge of a locking shoulder 407 of the pawl 396. When the pin 402 of the pawl 403 in cooperation with the shoulder 401 brings the pawl 396 clockwise into the release position the locking section 407 above the latch 406 which prevents' Ib reverse rotation of the pawl 396 under the action of the spring 398 when the stylus has left 402 towards the end of the fourth operating cycle the shoulder 401 to the buttons 331 and 332 entirely in the unpressed position have returned.

When returning to the unpressed position, a pin on the shaft of the button 332 works with a beveled edge of the pawl. 406 together and rotates this pawl counterclockwise, whereby its upper end is removed from the path of the heel 407. The pawl 396 can therefore lie against the bend 395 under the action of its loading spring. As the credit balance key is transferred to the printed layer 332 by pressing the _go intermediate loan balance key 331, only the release of the pawl 406 is required by the key 332nd

In order to prevent that the engine is operating, before diie Kreditsaldotasie 332 fully depressed and locked in the depressed position, the pin engages 375 (Fig. 21) which forms the pivot pin between the couplings _lo "lung rod 111 and the rod 374 , into a curve slot in the upper end of a rod 409, the lower end of which is hinged to the lever 65. Wird.nach removal of Klinke_357 from the lever _los 359 turned this clockwise and ^data:> pushed by the rod 374 to the right (Fig. 21), the upper end edge of the rod 409 passes under a pen 415 of the pawl 396 connected plate 416. _Ilp The pin 41S prevents an upward movement of the rod 409 and thus a release movement of the lever 65 in the counterclockwise direction (see also Fig. 3) until a button 332 is completely pressed and the pawl 396 in the counterclockwise direction < Has taken a blocked position. The plate 416 participates in the counter-pointer rotation of the pawl 396 and removes the pin 415 from the path of the front edge of the rod 409 so that nothing stands in the way of counter-pointer threing of the lever 65.

Tax institution for -that Arithmetic unit

As mentioned earlier, through. Press the credit balance button 332 (Fig. 23) the latch 346 brought out of engagement with the lever 349, so that this lever and the shaft 352 move clockwise as shown in Fig. 23 and can turn in the direction of the gazette as shown in Fig. 15. There is an arm on shaft 352 417 (Fig. 15), the lifting edge of which 418 cooperates with a lever 284 peg 19 peg and swings out this and the lever 286 in a clockwise direction. As a result, the pawls 201 and 202 are in the path of lever 171 brought to the balancing mechanism for a final total drawing process. With arm 417 is a finger 420 connected to a pin 421 of the

• Lever 197 worked together to build the SaI-dierwerk for a subtraction process. At the beginning of the first work cycle The circumference of the cam disk 355 '(Fig. 23) allows for coating processes to interact with the roller 354, however, does not allow the finger 420 to come into contact with the pen 421 comes.

The zero stop pawls 120 (Fig.q ) are brought into the inoperative position during coating processes in the following way:

The clockwise rotation of the lever 286 (Fig. 15) turns a pin 323 into a Lever307 (Fig. 18) counterclockwise geschireht, creating a second pin

* 308 of the lever 307 is removed from the extension of a coupling pawl 309 rotatable on a slide, 291, so that its recess 316 can grip under the action of a spring 301 over the pin 317 of an arm 318. The arm 318 is rotatably mounted on a fixed pin 319 and lies down under the action of a spring ¹ 322 with a projection 320 against the roller 321 a mounted on the main shaft 91st Disk 303. If the disk 303 is now rotated clockwise; so it swivels the arm 318 clockwise, which pulls the slide 291 over the KupphingsJdinke 309 to the left. An extension of the slide 291 engages with one. Pin 292 in. A fork seat of an arm 293 fastened on a shaft 294. A number of arms 295 are also fastened on the shaft 294, the pins 296 of which have lifting edges from, before jumps 297 and 298 of the locking slide 116 and the control slide ϊ 19 of the row of amount keys work together. By moving the slide 291 to the left, the shaft 294 with the arms 295 is rotated clockwise against the force of a spring 311 via the parts described, whereby the pins 296 via the control slide 119 move the zero stop pawls 120 (Fig. 9) into the inoperative position bring. This facility is effective during all four working cycles of an interim credit balance process and during the first three major games of a credit balance process. Of course, the zero stop pawls 120 must also be brought into the ineffective position during the fourth working cycle of a credit balance process. The means used for this purpose will be described later.

The amount switching elements 107 rotate. at When moving to the right according to Fig. 9, the wheels of the arithmetic unit no. 1 return to zero, whereby the amount switching elements 107 on the previously on the calculating wheels the amount in place. After this is done, a part 422 acts larger diameter of the cam disk 391 (Fig. 19) on a roller 423 one on the Shaft 70 attached arm 424 and pivots its arm as well as the shaft 70 counterclockwise. On the Two arms 425 and 426 are attached to shaft 70 (Fig. 20) 5 in their curved slots 427 the rollers 428 engage in two side walls of a frame 429 which are rotatably mounted on the shaft 108. The frame 429 carries the wheels 430 of the auxiliary storage unit, when the frame 429 is swiveled in the counter-clockwise direction with the amount switching elements 107 connected racks 431 (Fig. 9). When he turned the violin pointer If the arm 425 (Fig. 20) meets a pin 432 of a locking bar 433 (Fig. 9) and disengages them from the storage gears 430 after they have been connected to the racks 431 in Are engaged. The locking rail 433 is rotatably housed in the frame 429 and is held in engagement with the storage gears 430, normally by a spring. When they move back into the rest position, the amount switching elements 107 rotate the storage wheels 430, which were previously at zero, counterclockwise by the complement amount of the coating that was previously on the balancing mechanism.

Towards the end of the first working cycle, a part 434 with a smaller diameter leaves the 3S5 lifting disc (Fig. 23) in interaction with the roller 354 that the spring 353 the shaft 352 a little further jm Rotates clockwise, the. Finger 420 (Fig. 15) hits the "pin 421 and the Lever 197 rotates clockwise to the balancing mechanism in the manner described for select a subtraction operation. The part 422 (Fig. 19) of larger diameter the hub row 391 holds the storage wheels during the right movement according to Fig. 9 of the Betraigissichaltglieder 107 in the second. Work cycle, engaged with these.

.ti

The storage wheels 430 are rotated clockwise until there is a wide tooth of each wheel hits a stop in the frame men 429, thereby the storage wheels in the zero position stops and a move on the amount switching elements 107 prevents the consequent return to the complementary value of the coating are set., during the first work cycle from the SaI xo dierwerk was taken. The wheels of the balancing mechanism, which are used for a subtracting process are engaged in the amount switching elements 107 are made by the setting movement of the amount switching elements 107 rotated counterclockwise so that the complement amount of the actual coating is introduced subtractively into the arithmetic unit.

Before the amount switching elements 107 their return movement during the second working cycle begin in the rest position, the part 422 of larger diameter leaves the disk 391 (Fig. 19) the roller 423 so that a spring 435 (Fig. 20) is attached to one on the shaft 70 attached arm attacks the shaft-70 with the arms 42 5 uiid 426. clockwise can rotate to the storage gears from the racks 431 of the amount switching elements 107 to disengage. Towards the end of the second work cycle, the lifting disc 355 swivels f Fig. 23) in cooperation with the roller 354 the shaft 352 counterclockwise which removes finger 420 (Fig. 15) from pen 428. Nonetheless selects the lifting edge 418 in cooperation with the pin 419 the SaI dierwerk for a totals drawing process.

During the third work cycle by the setting movement of the amount switching elements 107 the actual coating has been removed from the rotary wheels of the balancing mechanism. While the amount switching elements 107 remain in their set position, a second part 436 becomes larger Diameter of the cam disk 391 (Fig. 20) effective, which in cooperation with the Roller 423 engages the feed wheels in the amount switching elements 107. As a result, will During the return movement of the amount switching elements 107, the actual coating in -, the storage wheels introduced.

During the first working cycle of a coating process, the part 436 meets the Lifting washer 391 (Fig. 19) onto the bend 437 of the pawl 431 and moves it out of the recess of the key shaft 332, so that the plate; 339 under the action of spring 342 regardless of the credit balance key 332 is moved upwards. As a result, the pawl 346 can also be placed under the bend 348 (Fig. 23) of the lever 349 grab when this and the shaft 352 through towards the end of the third work cycle a lifting thumb 438 of the lifting disc 355 swung counterclockwise will. This return movement of the shaft 352 causes the 'lifting edge 418 (Fig. 15) of the lever 417 removed from the pin 419, so that the levers 284 and 286 resume their rest position shown. It will that is, during the fourth work cycle of a coating process, the balancing mechanism that during of the third work cycle was set to zero, not i.n the amount switching element. 107 indented. The resetting of the lever 286 allows the lever 307 f Fig. 18) under the action of its spring 310 resumes its normal position and the recess 316 of the coupling pawl 309 removed from the pin 317, so that the disc 303 does not cause an adjustment of the slide 291 during the fourth working cycle would. However, it must be done during the fourth work cycle of a credit balance process the zero stop pawls 120 are disengaged so that the amount switching elements 107 and the type segments for the purpose of imprinting the actual negative coating can be adjusted by the storage wheels. This is done in the following way achieved:

The part hits during the third work cycle of a credit balance process. 436 (Fig. 19) of the cam disk 391 onto the roller 423 and thereby rotates the shaft 70 as well the arms 425 and 426 according to Fig. 8, 19 and 20 in the counter-clockwise direction and according to Fig. Ι S clockwise, with the arms 425 and 426 the wheels of the auxiliary spoke Engage racks 107 in the manner already described. At this Clockwise rotation of the arm 426 (Fig. 18) pivots its sloping edge 460 in cooperation with a pin 461 of the lever 307 this out counterclockwise, so that this the recess · 316 of the coupling pawl 309 reach over the pin 317 leaves. The coupling pawl remains during the first part of the fourth work cycle 309 m in their effective position, so that the slide 291 is pulled to the left as shown in Fig. 18 to the NuHansc.hlagklinken 120 (Fig. 19) in the manner already described to move out. Since the part 422 of the lifting disc 391 the arm 467 already during of the first work cycle of a credit balance process swiveled clockwise (Fig. 18), the beveled edge would be 460 den Move lever 307 downwards. In this period of time, however, this movement has none Significance more, since the lever 417 (Fig. 15) via lever 286 and pin 323

has moved lever 307 downward earlier. "

During the downward movement of the plate 339 (Fig. 23), the pawl 357 (Fig. 21) is also released, which engages under the bend 358 of the lever 359 when a part of larger diameter of the lifting disc 367 interacts with during the last part of the third working cycle the roller 366 returns the lever 359 counterclockwise to the normal position. By the return movement of the lever 359, the spring 377 is tensioned, with the pin 373 sliding ineffectively in the slot of the rod 374 because of this. Tent point the coupling pole. can not yet resume their effective position, but rather the pin 11 o of the arm 90 slides along a curved edge of the coupling member in. When, towards the end of the third working cycle, the pin 110 lies opposite the recess in the coupling rod, the spring 377 can rotate the coupling rod 111 clockwise and disengage it from the fixed pin 376 and engage the pin 110. As a result, the printing unit can work during the fourth work cycle.

The part 436 of the lifting disc 391 (Fig. 19) keeps the auxiliary accumulator in engagement with the racks 431 during the setting movement of the amount switching elements 107 in the fourth Ai-beitsSpiel, so that the accumulator gears 430 are brought into the zero position by the amount switching elements 107.

. As a result, the amount switching elements 107 (FIG. 9) and the type segments 58 are opened the actual overdraft set, the latter of which this amount on the bring the document wrapped around the paper roller 56 for printing.

After the storage wheels through the amount switching elements 107 during the first part of the fourth work cycle in the NuIllage are returned, the part 436 of the cam disk 391 (Fig. 19) leaves the roller 423 so that spring 435 (Fig.20) drives shaft 70 with arms 425 and 426 in a clockwise direction brings back into the position shown, whereby the storage wheels are disengaged from the amount switching elements and the locking bar 433 for the storage wheels is brought into the effective position. at his »return to the normal position against At the end of the third work cycle, the lever 359 (Figs. 3 and 21) brings the pawl 370 out of engagement with the pin 71, so that the latter grip behind the shoulder of the disc 69 can, if this by the lifting edge 92 of the

60 "arm 88 towards the end of the fourth work cycle is swung clockwise. The pawl 370 is only disengaged after the lifting edge 92 has pushed the roller 93 has left, so that the machine is shut down at the end of the third work cycle not happened yet.

During the downward movement of the coupling rod in during the fourth work cycle the pin 402 of the pawl 403 in cooperation with the shoulder 401 removes the pawl 396 from turn 395 (Fig. 28) so that the 'credit balance key 332 goes through the Spring 335 returned to the unpressed position will. When the button 332 (Fig. 19) has returned to its unpressed position. has, the bend 343 of the coupling pawl 341 can be in the recess of the button 332 so that the plate 339 is connected to the button 332 again.

Intermediate credit balances

The only difference between an inter-credit balance and a credit balance operation consists in that during the fourth working cycle of an interim credit balance the balancing work for a subtraction process is brought into engagement with the amount switching elements 107. Since during this Period of time the wheels of the storage unit are brought into the zero position, the actual negative balance introduced subtractively in the balancing work previously set to zero, so that at the end of this process the balancing mechanism is set to the complementary value of the coating.

When you press the Zwischenkreditsaldotasee 331 (Fig. 21) take their lengthways braid Credit balance key 332 via pins 336 and 337 so that pawl 396 engage via bends 394 and 395 can to keep both buttons in the pressed position '. Here brings the plate 339 (Figs. 19 and 23) pawls 346 and 357 in the same way with the levers 349 and 359 disengaged, as if the i ° 5 credit balance key 332 had been pressed alone were. A pawl 439 (Fig. 21) is rotatably seated on the inter-credit balance key 331, which can reach under the pin 336 under the action of a spring 440. Is the 11 " If button 331 is in its non-pressed position, an extension 441 of the pawl 439 lies down against the bottom edge of the keypad panel 76 and holds the pawl 439 out of engagement with it the pin 336 so that the credit balance key 332 is independent of the intermediate credit balance key 331 can be pressed. Pressing the inter-credit balance key will the extension 441 removed from the underside of the keypad plate 76 so that the pawl 439 reaches under the pin 336 in order to connect the buttons 331 and 332 to form a unit.

The two-way credit balance key 331 carries a pin 442 (Figs. 23 and 27), which with an L-shaped recess 443 a. on a pin 445 rotatable pawl 444 cooperates. If the inter-credit balance key 331 is not pressed, the holds Pin 442 in cooperation with the approximately vertical part of the recess 443 an extension of the pawl 444 below a pin 447 of the pawl 346th Is therefore, with button 331 in the unpressed position, pawl 444 does not act in any way on the latch 346, which works in the same way as for the credit balance transactions described.

Pressing the two-way credit balance button 331 puts the pin 442 in the approximate position horizontal part of the recess 443. As a result, a rotating fire 446 turn the pawl 444 'counterclockwise and adjust it as shown in Figs. 25 and 27 bring the extension directed to the right into the path of the pin 447 to a. Backward movement of the pawl 346 under the action of the spring 347 when the plate 339 is moved upward.

The first three work cycles of an interim credit balance run in the same way as the described first three work cycles of a credit balance process. However, if towards the end of the third work cycle of an interim credit balance the thumb 438 (Fig. 23) of the lifting disc 355 in cooperation with the roller 354 returns the lever 349 and the shaft 352 to the normal position, the pawl can 346, the pawl 444 placed in front of the pin 447 in the inoperative position is held, the. Do not hold lever 349 in its normal position. As a result, rotates the lever 349 again clockwise until its roller 354 on the peripheral part 44S of the lifting disc 355 hits. The peripheral part 44S has "the same half-diameter as the peripheral part 434. It leaves so a rotation of the shaft 352 so great that the finger 420 (Fig. 15) on the Pin 421 hits and lever 197 clockwise swings out to select the balancing unit for a second subtraction process. As a result, the wheels of the "balancing works" in the first part of the fourth work cycle before the setting movement of the Amount switching elements 107 engaged in this (Fig. 9). Since at the same time the actual The storage gears containing the coating are turned back to zero, the actual Overlay deducted from zero in the balancing work, so that in this the complementary amount of the actual coating appears.

In the last part of the fourth work cycle of an interim credit balance process occurs Pin 449 (Fig. 23 and 27) of the lifting disc 355 on an extension 450 of the pawl 444, swings it clockwise and removes its right appendage from the path of the pin 447, so that the pawl 346 under the action of its loading spring 347 the in Fig. 27 drawn position can resume, in which the pin 447 is above of the right extension of the pawl 444 is located. In this position the prevents Pin 447 a Gegencnzeigerdirehung the pawl 444 under the action of the spring 446, when the Pin 449 leaves the extension 450. Arrives towards the end of the fourth work cycle Lifting thumb 451 of lifting disc 355 (Fig. 23) on roller 354 and brings lever 349 as well as the shaft 35-2 counterclockwise back to the normal position, so there. " engage pawl 346 behind bend 348 and "lever 349 and shaft 352 in." the normal position can hold. During the downward movement of the coupling rod 111 (Fig. 21) during the fourth working cycle, the pin 402 removes in cooperation with the shoulder 401 the locking edge 399 of the pawl 396 from the bends 394 and 395 of buttons 331 and 332, so that these buttons are under the action of their loading springs take up the unpressed position again. When the button 331 is moved back, the Pawl 439 by the impact of its extension 441 on the underside of the keypad plate 76-removed from pin 336.

Locking device for the credit balance key

If there is a positive amount in the balancing work or if it is at zero, it is So if there is no overdraft, the credit balance key is locked against being pressed. There the two-way credit balance key cannot be printed without the credit balance key, so the two-way credit balance key is also locked. When the arithmetic wheel of the highest Significance of the balancing mechanism when rotating in the subtractive direction from zero to When you turn nine, the credit balance key is released and the balance key is released at the same time locked against depression. If an amount is added after an overlay inserted into the balancing mechanism large enough to undo the coating, so when the highest-digit arithmetic wheel goes down from nine to zero, it becomes more additive Direction the credit balance key locked again against pressing and at the same time the balance key released again.

Since when the balancing mechanism is reset, the highest-digit calculating wheel is not

ti'ven goes from nine to zero, but rotated to zero in the subtractive sense the locking device for the credit balance key is not in the effective position brought, rather, the locking device is · in a manner to be described by the triggering of the credit balance button made effective.

Since at the end of an interim loan process the supplementary number of the coating is in the balancing works, it is desirable that the balance key remains locked and the credit balance key remains unlocked. As a result, will with the intermediate credit balance key pressed, the facility that is activated by pressing the credit balance key the locking device would reset, rendered ineffective.

If the highest arithmetic wheel 204 (Fig. 11 and 12) of the balancing works in the subtractive sense from zero to nine, so swings one of the tens teeth of the tens disk 207 the associated tens counter pawl 206 in a clockwise direction and removes its turn 454 from a protrusion one on one Cross rod 456 rotatable adjusting member 455 for the cover shaft 466. After removal the bend 454 from the projection of the adjusting member 455, a spring 457 rotates this clockwise until its downward extension 458 touches bracket 452.

After the balancing mechanism is disengaged from the amount switching elements, the oscillates Clamp 452 clockwise into the position shown in Fig. 13 to carry out to allow the ten circuit. This takes on this clockwise rotation of the bracket 452 Adjusting member 455 part under the action of spring 457, its shoulder in cooperation with a bend 459 of an arm attached to a cover shaft 466 465 swings out this and the shaft 466 counterclockwise. On the cover shaft 466 is an arm 467 (Figs. 8, n and 15) attached to it by a rod 468 is connected to a slide 469. The slide 469 is open with a fork slot guided by a fixed pin 470 and on a locking lever 471 rotatable on the pin 281 , hinged. The counter-clockwise rotation of shaft 466 as shown in Figs. 11 and 15 becomes The locking lever 471 is swiveled counterclockwise via the parts described, thereby turning its 472 into a recess 473 in the shaft of the balance key enters row 102. ' This prevents the balance key from being depressed. if the balancing works is overdrawn. If the cover shaft 466 is rotated clockwise as shown in FIGS. 2 and 8, it pivots one attached to the right end of this shaft. Arm 474 over a rod 475 a pawl 476 rotatable clockwise on pin 397 (Fig. 23) and removed her paragraph 477 from the turn 395 of the credit balance key 332. Simultaneously with the locking of the balance key so the credit balance key 332 is released so that they can be pressed to initiate a credit balance process. Since the inter-credit balance key33i Without the credit balance key 332 cannot be pressed, the pawl 476 also locks the inter-credit balance key at the same time 331.

If an amount exceeding the overdraft is added to the overdraft inserted, the cover shaft 466 (Fig. 14) is in a known manner in the Normal position returned to release the balance key and the credit balance key to lock against depression. During the transition of the highest-digit calculating wheel 204 of the balancing swing from nine to zero in namely, in an additive sense, one of the tens teeth of the tens disk 207 removes the bend 478 of the counter pawl 205 (Fig. 14) from a projection on the cross bar 456 rotatable return pawl 480, which is under the action of a spring 481 places with its projection 482 against the reset bracket 452.

The bracket 452 becomes after the disengagement of the wheels of the balancing mechanism from the amount switching elements 107 swung out clockwise, the projection 479 meets the Pawl 480 under the action of the spring 481 on the bend 483 of the arm 465 and brings this arm and cover shaft 466 clockwise as shown in Figures 11 and 14 back to the normal position, whereby the bend 472 of the locking lever 471 from the Recess 473 of the balance key removed and this is thus released again. Simultaneously this resetting of the cover shaft brings the shoulder 477 of the pawl 476 under the bend 395 and the credit balance key 332 and the inter-credit balance key 331 are locked against being pressed, no

To the overburden shaft 466 also with credit balance processes. in which only a reverse rotation of the highest digit calculating wheel of the balancing works is done to zero, to bring back to the normal position, is the following Establishment met:

By pressing the credit balance key 332 (Figs. 23 and 24) you get to the turn 395, below the paragraph 48 5 of a return arm 486, which has a longitudinal slot is guided by the pin 397 and is normally supported by a spring 487 in the manner shown in Fig. 24.

i6

placed lower position is held. When the turn 395 is below the paragraph 485, a spring 488 engaging the upper end of the arm 486 rotates turn this counterclockwise and leave paragraph 485 over bend 395 !to grab. If during the fourth work cycle of a credit balance process the in Fig. 21 and 25 disengages the pawl 396, so brings the spring 335, which is much stronger than the spring 487, the credit balance key 332 in the unpressed Position backwards and takes the arm 486 with it, as can be seen from Fig. 23. A bend 489 of the arm 486 pivots, which engages behind the pawl 476 and slides along its sloping edge, this in the Counterclockwise and brings it from the inoperative position according to Fig. 24 to the effective position according to Fig. 23. By this counter-clockwise rotation of the pawl 476 the cover shaft 466 is also brought back into the basic position via the rod 47 5, to remove the locking lever 471 from the balance key to move out.

Is used during the machine cycle immediately following the credit balance cycle if the arm 90 swings out counterclockwise, it hits a curved edge 490 of this arm on a curved edge 491 at the lower end of the arm 486. As a result arm 486 is rotated clockwise and shoulder 485 from the bend 395 removed so that the spring 487 can pull the arm 486 down into the normal position according to FIG. After the arm 90 at has released arm 486 on its return movement, spring 488 brings the upper end of arm 486 into abutment with bend 395 the credit balance key 332. If during a credit balance process the parts assume the position shown in Fig. 24, thus the arm 90 disengages the shoulder 485 of the arm 486 with each working cycle with the bend 395. When the arm 90 moves back, however, the Paragraph 485 every time over the turn 395, including the last one Working cycle before the pawl 396 is disengaged.

This means that the Saldierwerk be at an intermediate loan balance process / at the end again in coated ^state. Place, the pawl remains locked 476 in the in Fig shown inoperative position and 24 the balance button to press, sitting on the bridge loan balance key 331 (Fig. 21) rotatable a pawl 492 held in contact with pin 334 by its loading spring. Pressing the inter-credit balance button 331 removes the pawl 492 from the pin 334 so that it can rotate counterclockwise until its rounded nose meets a pin 493 of the arm 486. When the arm 90 rotates in the opposite direction during the first working cycle of an interim credit process, the edge 490 swings out the arm 486 in cooperation with the curved edge 491 and removes the shoulder

485 from the bend 395, see above, the pin 493 slides over the hook of the pawl 492, the immediately reach behind the pin 493 and your arm

486 stops outside of the path of turn 395 of credit balance button 332.

Since the pawl 492 the shoulder 485 of the arm 486 when returning together the two buttons 331 and 332 in the unpressed position so long outside the web the turn 395 stops until this turn has left the area of paragraph 485, If the arm 486 is not taken along by the button 332 and therefore the pawl 476 cannot move into its operative position bring. This must therefore remain in the position shown in Fig. 24. After the Upward movement of the button 332, the turn of which 395 has left the area of the shoulder 485, the pawl 492 is hit by impact on pin 334 disengaged from pin 493 of arm 486.

Selection of adding units for addition during the credit balance and temporary processes

If the paper trolley is set to the balance column of the receipt, in which all balances including the credit and interim credit balances are printed, so a paper carriage stop works together with a feeler lever and selects the adder no. 2 for an addition to receive a sum of the new balances. Because this sum of new balances in the end is used for control purposes over a certain period of time, both positive balances as well as the complementary values of the negative balances are collected. As a result, the adder no. 2 must no during the first working cycle Loan or an inter-credit balance process indented for an addition process will. However, since the paper cart during the four work cycles of a credit or of an interim credit balance remains set to the balance column, this would selected adder no. 2 during each of these four work cycles in the amount switching elements 107 are indented. To prevent this from happening, the following facility has been implemented :

If the paper trolley 55 (Fig: 2) is brought into the balance column, it lifts on the square bar 494 located paper trolley to S'Chlag 510 over a on a fixed Pin 496 of the machine frame rotatable feeler lever 495 a pull rod 497 (Fig. 16) whose lower end is connected to the lever 498. By lifting the drawbar 497, the lever 498 is disengaged from a rotatable on a fixed pin Control lever 499 brought, the pin 500 of which with a protrusion · animal push rod 179 is working.

Is during the first work cycle of a credit or interim credit balance process The curved edge 183 of the engagement disk 173 away from the slide 182, the control lever 499 can move under the action its load spring against the clock

ao turn clockwise, whereby the pin 500 out of the area of the upper extension of the driver pawl 501 is removed, the rotatable is seated at the upper end of a lever 502 rotatable on the disk 173.

If, during the clockwise rotation of the disk 173, the square pin 503 hits the lower front edge of the driving pawl 501, this is carried along in a clockwise direction. Via a rod 504, 502 prevents the lever with an attached to a shaft 506 arm 505 comparable _#, the shaft 506 is rotated clockwise to engage around the wheels of the adder no. 2 in the amount of switching elements 107 after they finished their adjustment movement to have. During the return of the amount switching elements to the 'zero position, the complementary amount of the credit or inter-credit balance is added to the adder No. 2. The engagement device for the adder Nx. 2 works in the same way as the one already described for the balancing work.

Towards the end of the first working cycle, the disk 173 pivots as it moves back counterclockwise (Fig. 16) over the sliding piece 182 the lever 180 clockwise · which the rod 179 upwards and pushes the control lever 499 back to the normal position via the pin 500.

brings. Since the lever 498 'during all four working cycles out of engagement with the Lever 499 is held, the adder would during each of these work cycles No. 2 to be indented.

To prevent this, the arm 114 attached to the shaft 133 engages with a pin 507 (Fig. 2 and 8) into a longitudinal seat of a rod 508, which on one End of a bracket 509 rotatable on a shaft 257 is articulated. The other arm of the bracket 509 engages with a pin 515 (Fig. 8, 15 and 16) in the longitudinal slit of a Rod 516 with a second longitudinal seat is guided on a fixed pin 517. One between pin 515 and the rod 516 tensioned spring 518 normally holds the right end of the as shown in Fig. 15 and 16 left longitudinal slot in contact with pin 515.

During the: first work cycle, the Clockwise rotation of the disk 173 causes a downward movement the push rod 179 by the control lever turned in the counterclockwise direction 499 to. This will get a pin 519, which is on the upper end of the push rod 179 is located in the area of an extension 520 of the rod 516. As the coupling rod in (Fig. 21) for credit and for Intermediate credit balance operations is disengaged from the pin 110 of the arm 90 and therefore shaft 133 during the first three cycles of a coating operation remains at rest, arm 114 and the pen 507 does not move. They therefore hold an extension 521 (Figs. 2 and 8) of the Rod 508 in the path of a pin 522 of the arm 138, through which, as already described, the alignment device for the amount switching elements 107 is moved. Swings against At the end of the counter-pointer rotation of the arm 90, the roller 164 in cooperation with the Curve slot 137 the arm 138 in a clockwise direction off, the pin 522 meets the extension 521, pushes the rod 508 to the right according to Figs. 2 and 8 and rotates the bracket 509 clockwise, as shown in Fig. 15 and 16 counterclockwise.

Since at this point in time the push rod 179 (Fig. 16) is in its lower position is located, so prevents the pin 519 in cooperation with the. Appendix 520 a Adjustment of the rod 516.- As a result, the counter-pointer rotation of the Bracket 509 only the pin 515 in the The longitudinal seat is moved and the spring 518 is tensioned. The disk 173 returns to its normal position towards the end of the first working cycle back, it moves the push rod 519 upwards, so that the tensioned spring 518 no the rod 516 can pull to the left, whereby the extension 520 comes under the pin 519 and the control lever 499 during the holds the remaining three work cycles in the drawn non-adjustment. Will ** 5 now the shaft 91 and the disk 173 im If the clock swings out in the direction of the clock, the pin 500 becomes the driving pawl 501 held outside the path of the square pin 503 so that no movement is transmitted to the arm 505 and the shaft 50 & will.

The bracket 509 is encompassed by an arm 523 (Fig. 10j with a recess rotatable on the shaft 257 ⁾ Bracket 509 is swung out clockwise. A pawl 271 is guided with a longitudinal slot on a pin 270, the bend 273 of which is normally held in contact with the lower edge of a recess in the rod 269 by a spring 272. During the clockwise rotation of the drive shaft 133 for the printing unit, an arm attached to it swivels: 246 by means of a pin 274 a lever 275 rotatable on a fixed pin 276, likewise clockwise, so that the upper end of the lever 275 comes to the right of the pawl 271, which is passed through the arm 523 is brought into the position shown in Fig. 10. When the arm 246 moves back, the lever 27 5 returns the rod 269 to its normal position via the pawl 271, with its pin 268 ü By means of the arm 523, the bracket 509 and the part connected to it are returned to the position shown. This return movement only takes place during the fourth work cycle, since the coupling rod 111 (FIGS. 2 and 8) is not connected to the arm 90 again until the end of the third work cycle. One at the lower end of the arm 523 rotatable

• Bare spring-loaded pawl 525 holds in cooperation with the shaft 264 the arm 523 and the bracket 509 in the respectively set Fixed position.

Locking device for the credit balance key as a function of of the position of the Paper cart

A locking device is used to

• The machine would be prevented if the paper trolley was not set exactly on a column is. This locking device will simultaneously press the credit balance key 332 and thus also the interim credit balance key 331 prevented.

If the paper trolley is set on a column, the paper trolley stop has a nose 510 (Fig. 2) a feeler lever 528 {Fig; 3) swiveled out by a Rod 529 is connected to an arm 530 mounted on a shaft 531. Dtirch the pivoting of the sensing lever 528 becomes the arm 530, the shaft, via the rod 529 531 and a fork arm 532 attached to it rotated counterclockwise. Of the Arm 532 includes a pin 533 with its fork slot on a fixed pin 535 rotatable Lock plate 534 and pivots it clockwise as it rotates counter-clockwise the end. The clockwise rotation of the lock plate 534 creates a shoulder of a square pin 536 is removed and a recess 537 is placed opposite this. Consequently the lever 80 is released for a release movement in the counterclockwise direction. Is the If the carriage is not set exactly on a column, the locking plate 534 will remain in their effective position and prevents movement of the lever 80.

The arm S32 is connected through a enggewundene spring 538 with a cash on the pin 397 rotatable ⁷ S pawl 539, the credit balance key is removed at a counterclockwise rotation of the arm 532 out of the path of the turn 395, so that the loan balance key 332 is pressed can. If the paper trolley is removed from its column position, a spring 540 acting on the pin 533 brings the locking plate 534 into the locking position shown and rotates the arm 532 clockwise Turn 395 brings the credit balance key 332.

If the pawl 539 were missing, one could still find it in its effective position Locking plate 534 press button 331 or 332 "and thereby release lever 359, without the machine being able to be started.
